Abstract: Example embodiments herein provide methods and Dual SIM Dual Standby (DSDS) devices including a first Subscriber Identity Module (SIM) and a second SIM for managing data communication. The methods include establishing, by the DSDS device, a Radio Resource Control (RRC) connection over the first SIM and performing data communication with a network entity. Further, the methods include detecting, by the DSDS device, an activity upcoming over the second SIM. Further, the methods include transmitting, by the DSDS device, a connection suspend indication to the network entity to suspend the data communication over the first SIM, wherein the connection suspend indication is transmitted on one of a Layer-1 control signaling channel, a Layer-2 control signaling channel, and a Layer-3 control signaling channel.

Abstract: Systems and/or methods for handling Radio Frequency (RF) resources between a Multimedia Broadcast Multicast Services (MBMS) stack and a non-MBMS stack in a Dual SIM Dual Standby (DSDS) device. The method includes operations of receiving, by an arbitrator module, an MBMS configuration from the MBMS stack, calculating, by the arbitrator module, one or more available RF occasions and a duration of each of the one or more RF occasions based on MBMS configuration, updating the non-MBMS stack information on the availability of the one or more RF occasions along with the corresponding durations in absolute time, and receiving information from the non-MBMS stack on completion of operations utilizing the one or more available RF occasions.
